Osprey Sirrus 34 Hiking Backpack - Womens
Ventilated comfort for longer days on the trail
The women’s Osprey Sirrus 34 in Sevres Blue gives you room for a full day’s hiking kit, with an adjustable fit and a suspended mesh backpanel that helps air circulate between your back and the pack. Its 34-litre capacity suits extended day walks when you need extra layers, food, water and wet-weather gear.
A wide panel opening makes packing and finding equipment straightforward. A separate lower compartment helps organise your load, while accessible hipbelt pockets and stretch side pockets keep smaller essentials close. An included raincover stores at the base, ready for a change in the weather.
Why choose the Sirrus 34?
- AirSpeed™ ventilation: a tensioned mesh backpanel and LightWire perimeter frame support the load while allowing cooling airflow.
- Adjustable women’s fit: the torso length, padded shoulder harness and hipbelt let you fine-tune how the pack carries.
- Easy organisation: front panel access, a lower zip compartment and dedicated pockets help keep your kit in order.
- Raincover supplied: built-in storage at the base keeps it handy when rain arrives.
- Durable recycled fabrics: a ripstop nylon body and tougher nylon base balance everyday trail use with material efficiency.

Carry system
The AirSpeed™ back system combines a supportive suspended mesh panel with a LightWire frame. A padded, full-yoke harness uses breathable spacer mesh and cut-out airflow channels, while load-lifter straps help balance the upper part of the pack. The padded, mesh-covered hipbelt connects smoothly with the backpanel, and its ErgoPull adjustment draws the belt securely around your hips to transfer the load.
